HYDROLYSIS AND STEAM REFORMING OF DIMETHL ETHER OVER COMPOSITE CATALYSTS OF H-MORDENITE AND COPPER SPINEL OXIDE

摘要

Dimethyl ether (DME) has remarkable potential for use innautomotive fuels, the generation of electric power, and domesticnapplications such as heating and cooking. Like LPG, DME is a gas atnnormal temperature and pressure, and can be transformed into anliquid when subjected to modest pressure or cooling. Moreover, theninfrastructure used for LPG can be readily adapted to DME due tontheir similar physical properties. DME has currently become anpromising candidate as a source of hydrogen in the reforming processndue to its high hydrogen to carbon ratio and high energy density.nDME is preferable to methanol (MeOH) because it is non-toxic andnnon-corrosive. In addition, DME can be catalytically reformed atnlower temperatures than ethanol and methane1-4. Lastly, due to thenhigh oxygen content, ultra clean combustion, and lack of noxiousncompounds such as sulfur, DME is a versatile and promisingnalternative to other clean, renewable, low carbon fuels. An excellentnreview of DME in the viewpoints of availability, economics, andnenvironment has been clearly demonstrated5.
